Patrixbourne Sand Mastic
Problem with your window and door surrounds in Patrixbourne? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Cement or filler used on old window joints that has cracked
- Crumbling sand mastic round a window
- Wind and rain getting in round a sash window
What happens if it’s left?
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. Around Patrixbourne, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.

About our sand mastic in Patrixbourne
Traditional burnt sand mastic blends with stone and brick surrounds. It suits period and listed homes, where modern sealant can look out of place. We work on tenement windows, sash and case windows and brick reveals, and the jobs we see most are old cement repairs round a window that have failed and wind and rain getting in round a sash window.
Homes in small places like Patrixbourne often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Big or small, you get the same one-year guarantee in Patrixbourne and across Kent.

Surface by surface
Sash and case windows
The mastic round a sash window is on show, so a neat, even finish matters.
Period and listed homes
On a listed home or in a conservation area, the right material matters. Sand mastic is often the preferred finish.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Clear gutters so water does not pour onto the windows
- Inspect the joints round the windows every year or so
- Ask the planning authority about consent for listed or conservation-area homes
- Take care around the mastic when scraping paint
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.

Is sand mastic better than silicone for my windows?

Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Sand mastic in Patrixbourne: local notes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Goodnestone Park (about 4 miles east) nearby, there’s older building stock in the area around Patrixbourne as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Bridge and Patrixbourne Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Bekesbourne station, any sash windows need sound mastic to keep draughts and rain out. Homes close to Church of St Mary include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
What we do, step by step
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for a single window, longer for several. Somewhere as small as Patrixbourne, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed
